CLOSURE FOR GRAlN-RECEPTAOLES.

SPECIFICATION forming part of Letters Patent N0. 755,859, dated March29, 1904.

Application filed January 15, 1903. Serial No. 139,236. (No model.)

T0 at whom, it may concern:

Be it known that I, ALBERT L. ELIEL, of Parlin, Middlesex county, NewJersey, have invented certain new and useful Improvements in Closuresfor Grain-Receptacles, of which the following is a full, clear, andexact description.

This invention relates to a closure for bins or cars that are adapted tohold grain or similar material, and particularly to closures that areadapted to be slid up out of the way in order to permit the exit of thematerial inclosed.

The invention further refers to a closure of the class specified thathas ameans for relieving the pressure on the door or closure, so thatthe act of opening the same is easier.

The invention refers more particularly to a specific form of relief inthe shape of smaller openings provided with doors placed conveniently inthe main door and to be opened previous to the opening of the main door.

The invention is also designed to provide a door of the class describedthat can be easily placed out of the way and manipulated withconsiderable freedom and ease.

Reference is to be had to the accompanying drawings, forming part ofthis specification,

in which similar figures of reference refer to similar parts throughoutthe several views.

Figure 1 is a view of a door provided with my new relieving means, andFig. 2 is a horizontal section on line 2 2 in Fig. 1. Fig. 3 is a frontelevation on a new door to be hereinafter described, and Fig. 4 is acentral vertical section of the same, and Fig. 5 is a partial section onthe line 5 5 in Fig. 3.

In'Fig. 1 I show a door 10 in dotted outline, which represents aclosing-door for bins of grain or grain-cars. This door 10 is adapted torest on the bottom of the car 11, and as now made these doors areadapted to slide up and out of the way to allow the grain to flow out.The grain in transportation settles and,

coupled with its weight, usually forces the door in its bearings sotightly that it is impossible to raise the same, and in most cases theoperator is compelled to destroy or damage the door in order to effectan opening. In my construction of a door I provide an opening oropenings which can be provided with a door 12, fitting snugly therein.In Fig. 1 I show two means of securing these smaller doors 12. Thesesmaller doors are hung by means of hinges 13 and can be looked as in onecase by a pivoted bar 14:, which is adapted to lock behind the clips 15,and can be securely tightened by means of a suitable cam device 1 1, or,as shown in the right-hand side of Fig. 1, the door 12 can be providedwith a socket 16, placed in line with a similar socket 17 on thecar-floor, and a pin 18 can be slid down to tighten the door. It willthus be seen that when it is desired to raise the door 10 the smallerdoors 12, which are comparatively easy of operation, can be opened,which allows the grain immediately adjacent to the door 10 to flow outthrough these smaller openings, thereby relieving the pressure behindthe main door, when it can be slid up out of the way and the emptying ofthe car completed in a short time. In Fig. 5 I illustrate a door 20,

made on this principle, having the side ears 20 and it has in turn thesmaller relievingdoors 21, hinged at 22, which can be secured by meansof the latches 23, or any other suitable device can be employed. Securedto the cars 20 are cords or ropes 24, running over the pulleys 29 andsupporting the counterweights 25. These counterweights can be boxed in,if desired. Running through perforations in the ears 20* are the chains26, supported at convenient points at the top and bottom, as at 27. Inthis way a door is provided the raising of which is facilitated by theopening of the doors 21, as described above for the doors 12, when it isdesired to raise the main door 20. It can be started, if necessary, bymeans of a bar placed under a clip 30; but if this is not necessary thedoor can be slid up by hand, the counterweights 25 making thiscomparatively easy and the chains 27 running through the openings in theears 20. When the door has reached the top, it can be tilted, as shownin outlines in Fig. 4:, and the bottom end of it swings upward andinward to engage a latch 28, which holds it in its raised position,

the chain 26 assuming the position shown at 26, enough slack beingprovided therein to allow of the twisting shown. This door being made,preferably, of corrugated iron or steel makes a comparatively light andstrong door, with the flexible means of support that allows of its beingeasily and compactly placed in its raised position.

It will thus be seen that I have devised a door provided with arelieving means that will very much facilitate the unloading of grainfrom receptacles adapted for its storage.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a closure for grain-receptacles comprising a door adapted tobemoved vertically and having ears attached to its opposed upper ends,and slack chains secured at their ends and adapted to pass through theears on the H door when the door is moved vertically, said chains actingto support one end of the door when the door is swung to anapproximately horizontal position by the binding and tightening of thechains due thereto.

2. In a closure for grain-receptacles, comprising a door adapted to bemoved vertically and having ears attached to its opposed upper ends,slack chains secured at their ends and arranged to pass through the earson the door, counterweights secured to the door, said chains acting tosupport the upper end of the door when the door is swung to anapproximately horizontal position by the binding and tightening of thechains due thereto, and means for securing the door in its approximatelyhorizontal position.

3. In a closure for grain-receptacles, comprising a main door, smallerdoors arranged in the main door, ears on the opposed upper ends of thedoors, slack chains secured at their ends and arranged to pass throughthe ears when the door is moved vertically, said chains acting as apivot when the door is swung to an approximately horizontal position,and supporting the door when it is swung by the tightening of the chain,and means for supporting the free end of the door in its approximatelyhorizontal position.

' 4. In a closure for grain-receptacles, a main door, smaller doorsarranged in said main door, the smaller doors each being provided with apivoted bar arranged to rotate parallel with said smaller door andtvengage clips attached to said main door when said smaller door isclosed, and a cam device situated in the center of said pivoted bar, andadapted to lock said pivoted bar against rotation.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ALBERT L. ELIEL.
